Advantages to widescreen LCD monitors?

I think that for a single-screen setup I find Widescreen useful for being able to fit more stuff horizontally and multitask, but I still prefer two 4:3 monitors to any other setup.

I regularly use three setups - my desktop on a 20" 4:3 Dell LCD (1600x1200), my laptop on a 15.4" 1920x1200 16:10 screen, and dual 19" LCDs at work for 1560x1024 (A 10:4 or 5:2 ratio). I prefer the Duals the most, followed by the laptop, followed by the 20". One thing to note is that I would go for quality over size any day - While Dell's LCDs give great sharpness and size for the money you can get them at, I am less than pleased with their color rendition. My Laptop (which, admittedly, is a Dell as well) has colors on par with my Trinitron CRTs, while the other Dell LCDs (2001FP at home, a pair of 1901FPs at work) feel washed out and are tough to calibrate correctly. If I had to do it over again I'd have gone for a Samsung or NEC - I've liked those much better when using them - even if it meant dropping to 19" or 17" for my desktop.

Jam it back in, in the dark.
